14 OPERATING MANUAL Cautionary Notes. Pressure Discharge Make sure to release the refrigerant from the A/C system with appropriate recovery equipment before disconnecting AC lines. Make sure to relieve the internal pressure first when working on compressors which are separate from the system.. Recycling Refrigerant Make sure to use an officially approved refrigerant recovering equipment to capture refrigerant properly and avoid any release to the atmosphere. Use recovery equipments designated for each different type of refrigerant. Do not use the same equipment for different type of refrigerants..3 During recovery of refrigerant Avoid eye and skin contact with the refrigerant. Use protective glasses and gloves when handling refrigerant and working on A/C system or compressor..4 Well-ventilated Area Make sure the area you work is well ventilated. Keep away from open flames or flammable materials. Refrigerants and oils can produce poisonous gases in the presence of a flame..5 Compressed Air Compressed air can cause contamination. Do not apply compressed air into the A/C system. R34a Gas / PAG Oil Safety guide for handling WANG auto compressors.. Make sure you follow the cautionary notes on section.. R34a refrigerant is not a threat for ozone depletion however it s a threat for global warming. Avoid releasing R34a gas to the atmosphere. It is mandatory to recover and recycle R34a gas. Do not use the same equipment for different type of refrigerants..3 Avoid mixing R34a gas with other types of refrigerants. It may cause significant damages in A/C system..4 We recommend Wang specified PAG lubricant oil for R34a to use with Wang Compressor. Using other random lubricants may cause significant damages in A/C system..5 Use R34a or PAG oil only in the systems specifically designated for R34a and PAG oil. The exceptions are described in Conversion from R to R34A AC systems..6 Moisture may cause significant damages in A/C system. The WANG recommended PAG oil for R34a system eliminates the moisture. - Keep the PAG oil container sealed properly after each use and maintain the isolation of the oil from air. - Make sure all the fitting are capped after A/C system maintenance. Never leave fittings uncapped. - After maintenance on compressor or R34a system, make sure to evacuate the system minimum 45 minutes before recharging. This enables the elimination of moisture by the PAG oil in compressor and system.

15 OPERATING MANUAL Cautionary Notes Wang Directives for R to R34a conversion. Run the air condition system with A/C blower at high speed for 5 minutes to maximize the amount of oil in the compressor.. R- refrigerant will be ready to be recovered. 3. Detach the compressor from the vehicle. 4. After removing the oil plug on compressor, drain the mineral oil in the compressor. Continue the draining process patiently until you drain as much drain oil as possible. 5. Use a socket wrench to turn the shaft on the clutch armature retaining nut. Make sure to discharge the ports and drain the mineral oil from the cylinder head suction. 6. Detach the R- receiver or accumulator dryer from the vehicle and discard. Maintain the oil draining from the A/C hoses as long as possible. A/C hoses older than 0 years are recommended to be changed. 7. Check the receiver or accumulator dryer and replace O-rings with the approved HNBR O-rings. 8. Change the receiver and accumulator dryers with R34a compatible models. Make sure the new ones contain XH7 or XH9 desiccant. 9. Remove any foreign materials found during the CCOT system maintenance. Install an inline filter in the liquid line. During the installation of the filter, maintain the oil draining from the A/C lines as long as possible. Replace the O-rings with the approved HNBR O-rings. 0. Make sure the A/C system and compressor are in good condition.. Make sure using the original PAG lubricant oil and the specified oil amount. SP-0 or SP-0 oils are recommended to be added in the compressors.. Change the oil plug O-ring on the compressor with a HNBR seal. 3. Make sure the plug seat and O-ring are clean and damage free before reinstalling the compressor oil plug. Plug torque: -5ft-lb (5-0N-m, 50-00kgf-cm). 4. Make sure all seals on the compressor ports are approved HNBR seals. 5. Install the compressor to the A/C system, evacuate at least 45 minutes to a vacuum of 9in, Hg. Use R- equipment to remove the R- gas from the mineral oil. 6. Make sure all equipment and service fittings are compatible with R34a. Replace all the equipments and fittings from R- to R34a compatible. 7. Install R34a compatible hoses and all the other necessary equipment. Re-evacuate the system for 30 minutes. 8. Recharge R34a gas to the system 5% less weight than the R- amount. Make a leak check under SAEJ68 procesure. 9. If any foreign material is found In the system, follow the instruction written on step 9 and run the system for 60 minutes to filter this material. Recover the material and dispose the filter, reconnect the lines, evacuate min 45 minutes and recharge the system. This process is not necessary for TVX systems. 0. Make sure the A/C system is working with the right temperature and pressure parameters. This gives an idea to understand the right amount of R34a gas is charged.. In case of the low cooling performance or high discharge pressure, add more condensing capacity to the A/C system. Electric fans and/or larger capacity condenser can be used.. Make sure all R- labels are replaced with retrofit R34a labels determined in SAE J660. 3
